za'iECIFICATIOE-T forming part of Letters Patent No. 307,880, datedNovember 1l, 1884-.

Application filed December-i6, i983.

To @ZZ whom it may concern:

Be it known that I, MICHAEL E. SULLIVAN, of New Bedford, county ofBristol, and Stateof lWIassachusetts, have invented an Improvement inRing-Spinning Frames, ot' which the following description, in connectionwith the accompanying drawing, is a specification.

IThis invention has for its object to effect the twisting of the yarnprior to its arrival at the traveler, which acts to wind the yarn uponthe rotating bobbin. i

The invention herein contained consists, essentially, in a spindlehaving a ring or race attached thereto below the bobbin and providedwith a traveler, and means to support said spindle, combined with aring-rail and a ring, and a traveler adapted to be moved on it by thedrag of the yarn, the latter traveler, by falling behind the speed ofthe spindle and its attached bobbin, acting, as usual, to wind the yarnupon the bobbin,while the ring and traveler carried by or rotated withthe spindle twists the yarn.

The drawing represents one of my improved spindles and attached ring andtraveler secured to a foot-step rail, a bobbin, a ring-rail, and ringand traveler, part of a roller-beam, a guide-board, anattached-yarn-guide, and the lower one of the usual front rollerscornmon to ring-spinning frames, the said roller, roller-beam,guide-board, ring and step rails being in section, a part of the bobbinbeing broken away to show the spindle. The under front roller, a,yarn-guide a', guide-board a2, roller-beam as, ring-rail b, ring bthereon, its traveler Z, ring-holder b, step-rail c, nut' c',spindle-support c, spindle c3, whirl c" thereon, bobbin o, anddriving-band d', are

.and may bc all as usual in ring-spinning frames, and preferably thespindle-support will contain a movable or yielding bolster of theRabbeth class.

In accordance with my invention, the spindle is provided with a ring orrace, e, which I shall denominate as the twisting-ring,77 it receiving,supporting, and guiding a twisting-traveler, e', which receives the yarny directly from the yarn-guide a, the said yarn extending from the saidguide down through (Xo model.)

the ring b', thence through the traveler or eye e', and up through thewinding-on traveler bZ to the bobbin c5. The twisting-ring e rotates atthe same speed as and in unison with the bobbin, but thetwisting-traveler or eye e falls behind or does not rotate as fast asthe ring, for its movement is retarded through the friction of thewinding-on traveler b2 on\ the usual ring, b. It is well understood thatit is necessary f or the winding-on traveler to travel at a less speedthan the bobbin, in order to effect the winding of the yarn. The heavierthe traveler bt the harder and closer the winding, yet in ordinaryring-spinning frames, wherein the yarn is not fully twisted between thesingle traveler carried by the ring-rail and the guide-eye or frontrolls, the traveler has to be made lighter than if the yarn were fullytwisted before reaching the winding-on traveler. The normal tendency ofthe twisting-traveler to travel at the same speed as the twisting ringand spindle so acts upon the yarn as to cause it to assist thewinding-011 traveler in its movement on the ring b, thus enabling theemployment of a much heavier winding-011 traveler, which is of greatadvantage, both in regulating the draft or tension on the yarn and alsothe hardness of the yarn wound on the bobbin, and it also lessens wearof the traveler on the ring. The two travelers described receiving theyarn, as shown, have a tendency to equalize the strain or tension on theyarn as the latter is being wound from the empty bobbin to the fulldiameter ot' the yarn load, and vice versa, or at the bottom and top ofthe traverse, forthe eXtra strain exerted at such times upon the yarndraws the twisting-traveler against the twisting-ring with greaterforce, thus inclining it to travel more nearly at the speed of thetwisting-ringand spindle, at which time the twisting-traveler acts withgreater power upon the yarn, and consequently upon the winding-ontraveler, and starts and carries it forward, thus decreasing thetension, Twisting the yarn before it reaches the winding-on traveler b2enables the said traveler to be made through the said traveler from theyarn-guide.

The ring,` b may be of any usual e0nstruction, as may also be thetraveler b2. The ring` may be placed in a holder at the upper side ofthe ring-rail. The race of the ring may be inclined to face the bobbin,substantially as in United States Patent No. 24,681.

I do not desire to limit my invention to the particular ring andtraveler c e', as instead of the said devices I may eniploy a ring,` ofany other Wellknown shape, with va suitable or other well-known travelerthereon about over or against which the yarn is held, and, if de--sired,the race of the ring may be as in United States Patent No.24,681, or No. 180,611, or N0. 204,832, Without departing from myinvention.

The ring-rail may be moved vertically in any Well-known manner and bywell-known appliances.

I do not broadly claim a main and an auxiliary ring, both of which arefixed or do not rotate; nor do I broadly claim a ring fixed withrelation to the spindle, but above the base of the bobbin and alwaysoccupying the same position with relation to the stationary ring.

A rotating spindle provided with a twisting ring or race attachedthereto below the bobbin, and a twistinggtraveler for the saidtwisting-ring combined with a movable ringrail, a ring thereon, and awindingbn traveler on the ring attached to the rail, the said travelersbeing adapted to receive the yarn and 'cooperate substantially asdescribed.

y In testimony whereof I have signed Iny name to this specification inthe presence of two subscribing,` witnesses.

MICHAEL E. SULLIVAN.
